SUMMARY:Algebraic Geometry Working Seminar | Boris Li | Filtered Deformatio
 ns\nof Trivariate Polynomial Rings
CLASS:PUBLIC
DESCRIPTION:BORIS LI\, UNIVERSITY OF WATERLOO\n\n_Filtered Deformations of 
 Trivariate Polynomial Rings_\n\nAmong non-commutative rings\, those satisf
 ying a polynomial identity\n(PI) are especially well-behaved. They share m
 any properties with\ncommutative rings\, which we understand well. Etingof
  asked whether\nevery filtered deformation of a finitely generated commuta
 tive domain\,\nover an algebraically closed field of positive characterist
 ic\, is PI.\nIn this talk\, we will answer this question of Etingof affirm
 atively\nfor deformations of polynomial rings in three variables. In the\n
 pre-seminar\, I will define and discuss the properties of filtered\ndeform
 ations\n\nMC 5403
